Title (EN) PHOTON COUNTING DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE COMPTAGE DE PHOTONS
Abstract:
(EN) The invention relates a photon counting device and method for counting photon interactions in a piece of converter material and addressing the issue of charge sharing. The occurrence of a charge sharing event is already detected upon the onset of the pulse, taking into consideration an onset of a pulse in a neighboring pixel within a preferably very short coincidence window. According to the invention, it is detected whether a pulse is being processed and one or more neighboring pixels are scouted to decide whether a simultaneous interaction has been registered within a very short coincidence window.
(FR) L'invention concerne un dispositif de comptage de photons et un procédé pour compter des interactions de photons dans un morceau de matériau convertisseur et aborder le problème du partage de charge. La survenance d'un événement de partage de charge est déjà détectée lors de l'apparition de l'impulsion, en prenant en considération l'apparition d'une impulsion dans un pixel voisin à l'intérieur d'une fenêtre de coïncidence de préférence très courte. Selon l'invention, il est détecté si une impulsion est en cours de traitement et si un ou plusieurs pixels voisins sont éclairés afin de décider si une interaction simultanée a été enregistrée à l'intérieur d'une fenêtre de coïncidence très courte.
